Double Hung Replacement Windows
The most popular window style — two operable sashes for ventilation and effortless cleaning
Get a Free EstimateWhy Double Hung Windows Are the #1 Choice
Double hung windows are the most widely installed replacement window style in the United States — and for homeowners in the Quad Cities, they're the go-to choice for a reason. Both the upper and lower sashes are fully operable, giving you complete control over ventilation. Open the top to let warm air out, the bottom to let cool air in, or both at once for a full cross breeze on a pleasant Iowa or Illinois spring day.
What really sets double hung windows apart is cleaning convenience. Both sashes tilt inward, so you can clean the exterior glass surface from inside your home. No ladders required — even for second- and third-floor windows. This is a significant practical advantage that single hung windows simply cannot match.
Suburban Construction has been installing double hung windows throughout Davenport, Bettendorf, Moline, Rock Island, and the surrounding area since 1985. We handle everything from measurement and ordering to professional installation — backed by our lifetime workmanship guarantee.

Choose Your Glass Package
Nearly 80% of a window's surface area is glass — so the glass package you choose matters far more than the frame material. All double hung windows are available in three performance tiers.
Standard
FreedomMaxx Low-E HP
Double pane Low-E glass with argon fill. Substantially more efficient than single pane — the right choice for most budgets.
Upgraded
FreedomMaxx 7
Triple pane with two Low-E panes and two argon chambers. A measurable step up from standard double pane.
Best Performance
FreedomMaxx 10
Triple pane with two Low-E panes and two krypton gas chambers. Krypton is 2.9× denser than argon — our ultimate energy glass.

Upgrade to Triple Pane Krypton Glass
Our FreedomMaxxx 10 triple pane krypton system turns an already-great double hung window into the most energy-efficient replacement window available anywhere. Krypton gas fills both chambers between three panes of glass, insulating 50% better than argon. The result: up to 80% more energy efficiency compared to a standard double-pane window. Your heating and cooling bills will reflect the difference.
What to Expect During Installation
Our installation team measures each opening precisely before ordering your windows. On installation day, we remove and properly dispose of your old windows, install the new units with proper flashing and insulation, and ensure each window operates perfectly. We clean up thoroughly and walk you through the new windows before we leave. Most full-house installations are completed in a single day.
